Claims.

This invention relates to improvements in cartons and particularly to improvements in cartons of the knocked down type.

This application is a division of copending application Serial No. 403,376 for Cartons filed Julil 2l, 1941, now Patent No. 2,397,934.

In the past there has been provided hollow wall cartons such as disclosed in applicants Reissue Patent No. 21,158, dated July 25, 1939, on which the present application is an improvement. It is frequently desirable to provide hollow wall cartons of a shallow type whereby articles originally shipped therein maybe retained therein for display above the walls of said carton. In order to display the articles it is advantageous that the face of the article be inclined rearwardly from the observer and which position can be readily given to the articles by the formation of the carton or box displaying the same. The construction of the carton or box of the present invention fuliills these desirable qualities.

It is, therefore, the principal object of this in- .vention to provide a carton or boX of the knocked down variety having inclined inner supporting walls.

It is another object of this invention to Vprovide a knocked down carton or box which can be readily erected for use as a shipping and displaying container and wherein the displayed articles are disposed at an inclination to the plane of support of the container.

Another object of this invention is the provision of a box or carton for accomplishing the foregoing objects which is formed of a single blank.

Other objects and advantages of the present invention should be readily apparent by reference to the following specication. considered. in conjunction with the accompanying drawings forming a part thereof and it is to be understood that any modication may be made in the exact structural details there shown and described, within the scope of the appended claims, without departing from or exceeding the spirit of the invention.

In the drawings:

Fig. l is a plan view of an extended blank party broken away and partly folded from which the carton or box 4of this invention is formed.

Fig. 2 is a perspective View of a partly assembled carton utilizing the blank of Fig. l.

Fig. 3 is a vertical sectional view taken substantially longitudinally centrally of an assembled carton of this invention.

Fig. 4 a plan view of the carton of Fig. 3 as seen on line 4--4 on said Fig. 3.

Throughout the several views of the drawings similar reference characters are employed to denote the same or similar parts.

As was mentioned above this invention pertains to an improved carton of the knocked down type and particularly to a hollow wall carton wherein the inner wall member is inclined whereby articles may be mounted therein, while on display. In the following description references will be made to sides and ends, but it is to be understood Vthat these 'terms are used Amerely for convenience in reference land not as lmitating terms since the opposed longer sides are generally designated as sides while the shorter sides are frequently referred to as ends.

Specifically, the carton of this invention is formed 'from a blank indicated vby the reference numeral I'0 comprising a central Panel II which forms the bottom of the carton` The sides of the bottom vII are defined .by fold or score lines I2, I3, I4 and I5 which are indicated in the drawings by dash lines; and it should be here noted that all dash lines on the drawings Vindicate fold or score lines. Extending from fold lines I2 and I3 are portions I6 and I'I which, in the carton illustrated in the drawings constitute the carton sides, while extending from the score lines I4 and I5 are, respectively, portions I8 and I9 which form the end walls.

yPortions I6 and I1 are substantially identical in construction and it is deemed sufficient if but one of them be described .in detail, accordingly, the portion I'l is provided with score or fold lines 20, 2l, and 22 forming between them and the score lines I3 and outer edge of the portion I'I, panels 23, 24, 25 and 26. The opposite ends of the panel 25 are respectively defined by score lines 21 and 28 which, respectively, hingedly connect thereto tucki-ng flaps 23 and 30. Each of the flaps 29 and 30 has hingedly connected to it along its score or fold. lines 3l and 32, which 'are in line with side portion score line 2|, a spacer tab 33'and lill.

The end wall portions I8 and I9 are substan tiallyidentical in construction although the elements thereof are of different proportions which will be pointed out hereinafter while a description of the one of said portions is suicient for'the other. Accordingly, portion I9 is provided witha plurality of score or fold lines 35, 36 and 31 forming between them and score or fold line I5 .and the end of the blank, panels 38, 39, 4U and 4I'. The opposite endsof the panel 4U are respectively, in part, dened by score or fold lines 42 .and 43 which, respectively, hingedly connect to the ends of the said panel 40 spacer tabs 44 and 45. Further de- 3 lining the ends of the panel 40 are locking tabs 46 and 41.

A comparison of the panels of lthe end portions I9 and I8 will disclose that panel 4| of the end portion I8 is wider than the corresponding panel portion 4I of the end portion I9 while panel portion 39 of the end portion I8 is narrower than the corresponding panel portion 39 of the end portion I9 and the purpose for which will be pointed out subsequently.

The panel 25 of the side portions I6 and I'I are each provided near their ends and substantially adjacent the score of fold line 22 with inclined apertures 48 and 49 and the said panels are provided near one of their ends and adjacent the score or fold line 2| with a slit 59 thereby providing a tongue I.

Each of the side panels 23 is connected at its opposite ends with the adjacent ends of the adjacent end panel 38 by a mechanism referred to in the trade as a bellows corner. This bellows corner comprises a corner piece 52 connected by a score or fold line 53 to the side panel 23 and by a foldor score line 54 with the end panel 38. The corner piece 52 is further provided with a diagonal fold or score line 55.

The blank vIIJ is formed or cut from card or paper board material inV one piece with each of the extensions I 6 VandII extended as side extension I'I is illustrated and with the fold or score lines, above specifically set forth formed at the time vof `cutting the blank. AdhesiveY 5B is also at this time applied to the under side of the side portions panels 26. Actually the said side portions panels 26 and 25 are first folded on the score lines 2| onto the side portions panels 24.and23 before the said adhesive 56 is applied whereupon the said side portions panels 23, 24, 25 and V26 are folded about the score or fold line I3 onto the bottom panel I I which is the arrangement illustrated for side portion I6 in Fig 1 and whereby the side portions panels 26 are adhesively secured to the bottom panel I. It is in this condition that the cartons are shipped to the purchaser for subsequent use. n

In order to assemble the carton, the sides IB and I'I are raised from the illustrated folded position of side I6 t-o the upstanding position of the sides as illustrated in Fig 2 in which said carton sides are normal to the bottom panel. It will be noted that the sides are then provided With outer side wall members 23 normal to the bottom panel II, top wall members 2,4 extending parallel with the bottom panel II, inner sides wall members, formed by the panels 25,*extend`ing normal to the bottom panel II and with the outer panels 26 glued tothe bottom panel II. The tucking naps 29 and 3U are then arranged across the bottom panel with their-spacer flaps disposed parallel with the bottom. f

'Ihe end portions or walls I8 and I9 are then assembled to complete the carton. Bellows corner pieces or portions 52 are folded inwardly along fold or score lines 53 and 54 causing each of them to fold on itself about the diagonal fold or score line 55. This operation causes the end eX- tension` I8 and I9 to be disposed normal to the bottom panel II with the panels 38 forming the outer end wall members. The remaining portion of each end wall extension is then folded as follows. The endmost panel 4| is bent along score line 31 to be at right angles to panel 40. Panel 39 is then bent about score line 35 at right angles to panel 38 to form end wall top member and is therefore parallel with the bottompanel I I. The panel 40 is then bent about score line 36 toward the outer end wall member 39 thereby forcing the lower end of said panel andthe panel 4I toward the outer end wall member and to lie parallel with and on the bottom panel II. Due to the shortness of the panel 4I and when it contacts with the outer end wall member 33Y it causes the inner Vend wall memberrk'l to lie at an angle to the bottom other than a right angle and actually to have its lower end beneath the top or end wall panel 39 as clearly illustrated at the right hand end of Fig 3. In other words the inner wall member is inclined upwardly and toward the center of the assembled carton and provides an angle of inclination which is the angle of inclination of the articles or goods to be displayed ras illustrated in phantom lines at 5l in Fig 3.

With respect to the end wall portion I8 and having the opposite proportion in Widths of the panels 39 and 4| from lthat of lthe corresponding panels of the end wall portion I9 the inner end Wall inclines oppositely, namely, downwardly and toward the interior' or cen-ter ofthe assembled carton as clearly illustrated att-he left hand end of Fig. 3. Inv each instance, however, the inner wall member is inclined withrrespect to its outer wall'member.' Y

The end walls are retained against collapse first by side wall .tucking flaps 29 and 30 and their spacer flaps 33 and 34 which underlie the end wallsformed from end wall extensions and secondly by the tonguesv 5| which projecttoward one another from the tops of 'theinner walls members and around at the end wall panels 39 and 40 are folded. These parts are locked in the assembled positions by snapping the locking tabs 46 and 41, at the opposite ends of the end wall inner wall members` 49, respectively, into the inclined apertures 48Y and 49 of the side wall inner wall members 25.

In order toprevent Vthe disarrangements of the goodsror articles 51 upon removal, for example, of the rst one, there is provided in thel carton means for preventing the lower end of successive articles. from slidingforw-ard dueto their angular position. This means conveniently takes the form of a piece of so called corrugatedV board 58 whichnis provided transversely thereof with successive vundulations 59. As is readily apparent from an inspection. 0f Fig..3 the lower corner of articles 51 isr disposed in the kvalley be- Y tween successive ridges withv the bottom of` the article against the forwardundulation and with the rear side of the last article in the carton engaging the upper corner of the inner wall member of the hollow end wall. YWhile the standard corrugated board actually llsthe need fora means for maintaining the articles in the desired position it will be understood that a stepped member may be substituted therefore.V

It is believed that the foregoing clearlydis-` closes the construction .of ya carton or box for the purpose originally set forth and provides a construction which will accomplish the desired obiectsof this invention. Y l
